Step by Step explanation:
Amy runs a bike rental business. She currently charges $36 per bike
rental and averages 60 rentals a week for an average weekly income of
$2,160. She predicts that she may lose 2 rentals a week for every one-
dollar increase in the rental price,p. Amy writes the expression
- 2p-12p+2160 to model her prediction. Which of the following is
the equivalent expression to reveal the maximum income based upon
Amy's model?
Answer:
b
Step-by-step explanation:
The equivalent expression to reveal the maximum income based upon Amy's model is -2(p+ 3)²+ 2178.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
The model for Amy Situation is -2p²- 12p+ 2160
Now, - 2(p+ 3)²+ 2178
= -2p² - 18 - 12p + 2178
= -2p² - 12p + 2160
and, -2(p+ 6)² +2160
= -2p² - 72 - 24p + 2160
= -2p² - 24p + 2088
and, - 2(p-3)²+ 2178
= -2p² - 18 + 12p + 2178
= -2p² + 12p + 2160
Hence, the equivalent expression to reveal the maximum income based upon Amy's model is -2(p+ 3)²+ 2178.

DJ Davon is making a playlist for work; he is trying to decide what 12 songs to play and in what order they should be played. If he has his choices narrowed down to 14 blues, 25 country, and 21 disco songs, and he wants to play an equal number of blues, country, and disco songs, how many different playlists are possible
Answer:
3.63 * 10^19
Step-by-step explanation:
Given that :
Number of choices to select = 12
Category available :
Blues - 14
Country - 25
Disco - 21
To select an equal number of song for each category ; then 4 songs will be selected from each :
Using combination :
(14C4 * 25C4 * 21C4)
Since the order matters for the 12 selected songs ; it thus requires 12 permutation
Thus ;
(14C4 * 25C4 * 21C4) * 12!
nCr = n! / (n-r)!r!
Using calculator;
14C4 = 1001 ;
25C4 = 12650
21C4 = 5985
12! = 479001600
Hence,
(1001 * 12650 * 5985) * 479001600
= 36301596217286400000
=3.63 * 10^19

(2x-7)/57 = (x+4)/51 cross multiply expressions
51×(2x-7) = 57×(x+4)
102x - 357 = 57x + 228
102x - 57x = 228 + 357
45x = 585 divide both sides with 45

a flag pole that is 8 feet tall casts a shadow that is 6 ft long a nearby tree casts a shadow that is 21 ft long. How tall is the tree?
Answer:
The tree is 28 feet tall.
Step-by-step explanation:
It is given that:
Height of flag pole = 8 feet
Shadow of flag pole = 6 feet
Ratio of height to shadow = 8 : 6
Shadow of nearby tree = 21 feet
Height of nearby tree = x
Ratio of height to shadow = x : 21
8 : 6 :: x : 21
Product of means = Product of extremes
6x = 8*21
6x = 168
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{168}{6}\\x=28[/tex]
Therefore,
The tree is 28 feet tall.

Question:
James had 4/5 qt of milk. He drank 1/3 of the milk. How much milk did James drink?
Enter your answer, as a fraction in simplest form, in the box.
Answer:
[tex]Milk = \frac{4}{15}\ qt[/tex]
Step-by-step explanation:
Given
[tex]Total = \frac{4}{5}\ qt[/tex]
[tex]Drank = \frac{1}{3}[/tex]
Required
Determine how much he drank
To do this, we simply multiply the total by the fraction of milk, he drank.
i.e.
[tex]Milk = \frac{1}{3} * \frac{4}{5}\ qt[/tex]
[tex]Milk = \frac{1*4}{3*5}\ qt[/tex]
[tex]Milk = \frac{4}{15}\ qt[/tex]
Hence, he drank 4/15 qt

For runners in a race, a low time means a faster run. The winners in a race have the shortest running times. Is it more desirable to have a finish time with a high or a low percentile when running a race
Answer:
It is desirable to have finish time with low percentile.
Step-by-step explanation:
It is more desirable to have a low percentile for finish time for runners when running a race. A low percentile means a short time, which is faster.
When competing in a race, a low percentile finish time is preferable.
What is the relationship between speed and time?
Speed is the rate at which a distance changes over time. So speed and time are inversely proportional.
In a race, the person who runs faster will finish the race first. So a faster run takes less time.
Hence, it is more desirable to have a low percentile finish time during a race.
